There are approximately seven days after an update, my system started to behave strangely. Whenever I need to use a program that uses root access, eg:

mount partitiongpartedDate and Time SettingsNetwork Settingsetc ...

If I use the terminal commands that need root, for example:

sudo equo upgrade sudo nano /etc/filetxtsudo mv /etc/filetxt /root/filetxtI can mount other drives using the command line.I can even log in as root from the terminal.

Everything works normally!!!!!!!!!

I've had other updates and so far nothing. Does anyone have any idea how can I solve this problem?

Subject edited by Moderator, as I believe it was translated from Portuguese using Google Translate and the author meant 'Error with applications that need root', not 'Error with applications that accuracy Root' ('precisam', not 'precisão'!).

To explain better my problem, it's sufficient to think about the need to use a pen drive, on inserting the pen drive into the PC, it does not allow me to mount it, for this I have to use the mount command, specify the type of partition and where it will be mounted. Before it was much simpler, it was sufficient to go to dolphin or to the device manager and click on the disc. Another thing that I lost control of without "root", is the configuration of the network, now I cannot change my network preferences, before when something on the network was changed, it was necessary to enter the root password (sudo), now there is no way to do this via GUI and easily.

I administer 4 computers, 2 of them are used by children that do not have the root password for use, due to this problem they cannot use pen drives or memory cards. The third machine is used by my wife, who does not posess much knowledge of Linux, but knows how to use it day to day, in the company where she works the netywork is badly configured and to surf it is necessary to configure it manually, ip, dns and network mask. Imagine the hurdle it would be to explain to her how to configure a network via the terminal. The 4th machine is mine, and I by using the terminal and commands like "kdesu".

Alberto, if you have any idea of how to help me, I would be grateful, but in advance I thank you deeply for your help and willingness.

In other words, after upgrading he has lost the ability to mount a pen drive via the GUI (KDE), and he has lost the ability to change his network preferences via the GUI (KDE).

When I click on an unmounted pen drive in KDE's Device Manager or in a Dolphin window, the pen drive gets mounted. He is saying that it used to be that way for him too, but it doesn't work any more.

When I click on Edit in KDE 'Manage Connections', KDE pops up a window prompting me to enter the root user's password before allowing me to edit the network configuration. He is saying that it used to be that way for him too, but it doesn't work any more.
